1、Don\'t Rely on Plankton to Save the PlanetEncouraging plankton growth in the ocean has been touted by some as a promising way to remove carbon dioxide from the atmosphere. Its opponents fear that will damage the marine ecosystem, and now a computer model shows that the trick would also be remarkably inefficient.Adding iron to patched of ocean can make plankton bloom temporarily. The microscopic organisms suck up dissolved carbon dioxide from the water, which in turn is replaced by carbon dioxide from the air. As plankton die and settle on the ocean floor, their carbon is supposedly locked up in the seabed.Jorge Sarmiento from Princeton and his colleagues developed a complex computer model to analyze how factors such as ocean chemistry and water circulation would affect the process if 160,000 square kilometers of ocean were seeded with iron for a month. ______In their scenario, which covers an area 10 times as big as the largest experiment of this kind ever proposed, fertilizing the ocean removes 1 million tons of carbon from the atmosphere just 0.2 percent of the carbon dioxide humankind spews out each month. Rough estimates in the past have predicted similarly disappointing results."These are newer and better models," says Sallie Chisholm, an environmental engineer from the Massachusetts Institute of Technology."Butthe take-home message is the same. Ocean fertilization is not the answer to global warming."【单选题】

A.Its opponents argue, however, that it will stop global warming.

B.Its opponents fear that will damage the marine ecosystem, and now a computer model shows that the trick would also be remarkably inefficient.

2、Houses of FutureWhat will houses be like in thirty years\' time? No one really knows, but architects are trying to predict what our home will be likeE. Future houses will have to be flexible. In thirty years\' time even more of us will be working at home. So we will have to be able to use areas of the house for work for part of the day and for living for the rest. Families grow and change with children arriving, growing up and leaving home. The house ofthe future will have to grow and change with the familyF, nothing will be as fixed as it is now. The house will always be changing to meet changing needs. Everyone agrees that in thirty years\' time we will be living in "intelligent" houses. We will be able to talk to our kitchen machines and discuss with them what to do. Like this, "we\'ll be having a party this weekend. What food shall we cook?" ______. We will be able to leave most of the cooking to the machines, just tasting things from time to time to check. The house of the future will be personal-each house, you will be able to change the color ofthe wall easily, you won\'t have to paint them, you\'ll be able to tell the wall to change the color! And if you don\'t like the color the next day, you will be able to have a new one. The only thing you won\'t be able to do is moving the house somewhere else.【单选题】

A.you will be able to change the color ofthe wall easily

B.The only thing you won\'t be able to do is moving the house somewhere else

C.And the machine will tell us what food we will have to buy and how to cook it

D.what our home will be likeE

E.The house ofthe future will have to grow and change with the familyF

F.he kids might take their bedrooms with them as they have

正确答案:C

答案解析:意思是“智能机器会告诉我们需买的食材和烹饪的方法”，与文章中智能机器如何工作相符。

3、Looking to the FutureWhen a magazine for high-school students asked its readers what life would be like in twenty years, they said: Machines would be run by solar power. Buildings would rotate so they could follow the sun to take maximum advantage of its light and heat. Walls would "radiate light" and "change color with the push of a buttons." Food would be replaced by pills. School would be taught "by electrical impulse while we sleep." Cars would have radar. Does this sound like the year 2000? Actually, the article was written in 1958 and the question was, "what will life be like in 1978?". The future is much too important to simply guess about, the way the high school students did. ______ By carefully studying the present, skilled businessmen, scientists, and politicians are supposedly able to figure out in advance what will happen. But can they? One expert on cities wrote: Cities of the future would not be crowded but would have space for farms and fields. People would travel to world in "airbuses" all-weather helicopters carrying up to 200 passengers. When a person left the airbus station he could drive a coin-operated car equipped with radar. The radar equipment of cars would make traffic accidents "almost unheard off\'. Does that sound familiar? If the exert had been accurate it would, because he was writing in 1957. His subject was "The city of 1982". If the professionals sometimes sound like high-school students, it\'s probably because future study is still a new field. Here is an example for future study. Economic forecasting, or predicting what the economy will do, has been around for a long time. But there have been some big mistakes in this field, too. In early 1929, most forecasters saw an excellent future for the stock market. In October of that year, the stock market had its worst losses ever, ruining thousands of investors who had put their faith in financial foreseers. One forecaster knew that predictions about the future would always be subject to significant errors. In 1957, H. J. Rand of the Rand Corporation was asked about the year 2000, "Only one thing is certain," he answered. " Children born today will have reached the age of 43."【单选题】

A.In early 1929, most forecasters saw an excellent future for the stock market.

B.Children born today will have reached the age of 43.

C.Actually, the article was written in 1958 and the question was, "what will life be like in 1978?"

D.So experts are regularly asked to predict accurately.

E.Scientists are 80 percent accurate in predicting the future.

F.The radar equipment of cars would make traffic accidents "almost unheard off\'.

正确答案:D

答案解析:第2段第1句说的是：预测未来很重要，不能像中学生那样猜测。本题的关键词是experts，他们不同于中学生，他们的预测应该是较为准确的。据此分析选项D是正确的。

5、Dung to DeathFields across Europe are contaminated with dangerous levels of the antibiotics given to farm animals. The drugs, which are in manure sprayed onto fields as fertilizers, could be getting into our food and water, helping to create a new generation of antibiotic-resistant "superbugs". The warning comes from a researcher in Switzerland who looked at levels of the drugs in farm slurry His findings are particularly shocking because Switzerland is one of the few countries to have banned antibiotics as growth promoters in animal dead.Some 20,000 tons of antibiotics are used in the European Union and the US each year. More than half are given to farm-animals to prevent disease and promote growth. But recent research has found a direct link between the increased use of these farmyard drugs and the appearance of antibiotic-resistant bugs that infect people. Most researchers assumed that humans become infected with the resistant strains by eating contaminated meat. But far more of the drugs end. up in manure than in meat products, says Stephen Mueller of the Swiss Federal Institute for Environmental Science and Technology in Dubendorf. ______With millions of tons of animals manure spread onto fields of crops such as wheat and barley each year, this pathway seems an equally likely route for spreading resistance, he said. The drugs contaminate the crops, which are then eaten. They could also be leaching into tap water pumped from rocks beneath fertilized fields.Mueller is particularly concerned about a group of antibiotics called sulphonamides. They do not easily degrade or dissolve in water. His analysis found that Swiss farm manure contains a high percentage of sulphonamides; each hectare of field could be contaminated with up to 1 kilogram of the drugs. This concentration is high enough to trigger the development of resistance among bacteria. But vets are not treating the issue seriously. There is growing concern at the extent to which drugs, including antibiotics, are polluting the environment. Many drugs given to humans are also excreted unchanged and are not broken down by conventional sewage treatment.【单选题】

A.They do not easily degrade or dissolve in water.

B.And manure contains especiaily high levels of bugs that are resistant to antibiotics he says.

C.Animal antibiotics is still an area to which insufficient attention has been paid

D.But recent research has found a direct link between the increased use of these farmyard drugs and the appearance of antibiotic-resistant bugs that infect people.

E.His findings are particularly shocking because Switzerland is one of the few countries to have banned antibiotics as growth promoters in animal dead.

F.They could also be leaching into tap water pumped from rocks beneath fertilized fields.

正确答案:B

答案解析:选项B中有两处提示：一是本句结尾处的he says，说明上文中必提到一个被引用的人；二是句首的And，这个词表明，这句的内容可能是前一句的延续。前一句引的S. Mueller说的话讲到，在肥料中滞留的药物比肉类产品中多得多。这句话则继续引用Mueller的话，进一步说肥料中对抗生素有抗药性的病菌含量特别高。
